Title: Magnetic thin film memory element and its recording and reproducing method
Inventor: NISHIMURA NAOKI
IPC: G11C11/15
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic thin film memory element which eliminates adverse effect of the diamagnetic field, preserves stabilized magnetized information, cuts the closed magnetic path off in recording, facilitates magnetization inversion, reduces power consumption and realizes a high degree of integration by forming a closed magnetic path when the external magnetic field is zero and holding the Curie tempera ture of the third magnetic layer lower than those of the first and second magnetic layers. SOLUTION: First, second and third magnetic layers 1, 2, 3 surround a non-magnetic layer 4. When the external magnetic field is zero, the first and second magnetic layers 1, 2 are anti-parallelly magnetized to form a closed magnetic path through the third magnetic layer 3. Data is recorded by the magnetic field generated a neighboring word line and at this time the temperature of the memory cell is raised by heat dissipation of the word line. By setting the Curie temperature of the third magnetic layer 3 lower than those of the first and second magnetic layers 1, 2, the third magnetic layer 3 loses the magnetism sufficient to form the annular loop of magnetization, the second magnetic layer for preserving magnetization information is made susceptible to magnetization inversion and thereby magnetization information is stably recorded, allowing small current recording.

The two ball bearings 8, 9 are fixed in a position where the coaxiality relative to the shaft 11 is the smallest, and hold that part by pressing the inner rings with the spring 14 for applying pre-load to them.
Patent JP-H06538-A (JP)
Title: Method for preventing generation of l-camber of blank
Inventor: UMADATE KENJI
IPC: B21D1/02
Filed: 1992-06-15
Abstract: PURPOSE:To prevent an L-camber from being generated on a blank stock by providing crowns so that in each work roll its crown rate changes from a large crown rate to a small crown rate in sequence from the inlet side of a sheet to its outlet side. CONSTITUTION:When the longitudinal camber of the sheet 1 is straightened, the crown rate is made large on the inlet side of a roller leveler 3. Therefore, the crown rate changes largely in response to large intermesh and work rolls 2 come into linear contact with the whole width of the sheet 1. Since the intermesh is large, a large load acts on the sheet 1 alternately in the reverse direction and the camber is corrected over the whole width. Further, since the crown rate is small on the outlet side of the leveler 3, the crown is changed even by a small intermesh and the work roll 2 comes into linear contact with the whole width of the sheet 2. Generation of residual stress is prevented over the whole width of the sheet 1.

Title: Mic isolator
Inventor: KOBAYASHI YUKIO
IPC: H01P1/36
Filed: 1987-06-24
Abstract: PURPOSE: To miniaturize the microwave amplifier circuit which uses this isolator, by providing capacitors between input-output sections and a resonating section.  
     CONSTITUTION: Chip capacitors 1 are provided between a resonating section 5 and input-output sections 6. Since the conductor patterns 2 of the input-output sections 6 are isolated from the resonating section in respect of the direct current, no electric current flows to a sub-carrier (which functions as a ground) 7 through a terminating section 4 even when a voltage is applied across the input-output sections 6. When a microwave amplifier circuit is constituted by respectively arranging MIC isolators 10 before and after a microwave amplifier 20, it is not necessary to provide a capacitor to the amplifier 20, because each of the isolators 10 itself is provided with chip capacitor 1. Therefore, the microwave amplifier 20 can be miniaturized.
